MAX5456, MAX5457 Stereo Audio Taper Potentiometers With Pushbutton Interface

The MAX5456 MAX5457 dual, logarithmic taper Digital Potentiometers feature a simple pushbutton Interface that controls volume and balance in Audio applications. Each potentiometer has 32 tap points and replaces mechanical potentiometers. Refer to the MAX5408-MAX5411 data sheet for SPI" versions of the MAX5456 MAX5457. Use the MAX5456 MAX5457 digital inputs with momentary contact single-pole/single-throw (SPST) pushbutton switches. Each input includes internal debounce circuitry and a 50k pullup resistor. The MAX5456 MAX5457 advance the wiper setting once per button push. Maxim's proprietary SmartWiper" control eliminates the need for a microcomputer to increase the wiper transition rate. Holding the control input low for more than 1s advances the wiper at a rate of 4Hz for 4s and 16Hz per second thereafter. The MAX5456 MAX5457 provide temperature coefficients of 50ppm/C end-to-end and 5ppm/C ratiometric and a nominal resistance of 10k per potentiometer. An integrated click/pop suppression feature minimizes the audible noise generated by wiper transitions. The typical total harmonic distortion plus noise (THD+N) for these devices is 0.01%. The MAX5457 features a 3-button Interface with a MODE-bar input that toggles between volume- and balance-control modes. An LED output indicates volume or balance mode. The MAX5456 features a 4-button Interface with separate inputs for up and down Volume Controls and left and right balance controls. The MAX5456 MAX5457 are available in 16-pin QSOP and 16-pin TQFN packages and are specified over the extended (-40C to +85C) temperature range.
